At Mai Taniyama's school, there is an old, abandoned building rumored to be cursed. Every time attempts are made to tear it down, a series of unexplained deaths occur, halting the demolition. Determined to prove the building is truly haunted, Mai and her classmates try to summon a ghost by telling stories. Though no spirits appear, they instead meet Kazuya Shibuya, a new 17-year-old student. While her friends are drawn to his good looks and polite demeanor, Mai remains skeptical.
After an incident, Mai learns that Kazuya leads Shibuya Psychic Research, a team hired by the school principal to investigate the alleged supernatural phenomena in the building. Because of her involvement, Mai is forced to temporarily assist Kazuya to avoid paying for the damage. Alongside other paranormal investigators—Houshou Takigawa, a former Buddhist monk; Ayako Matsusaki, a self-proclaimed Shinto priestess; renowned medium Masako Hara; and Catholic priest John Brown—Mai and Kazuya work to uncover the building's mystery before anyone else gets hurt.
